Rex and Bob's bathroom—with its tiny sink, dilapidated mirror, and dinky windowsill cluttered with toiletries—was lackluster and cramped, at best. The couple, who had been renovating their charming 1920s home one room at a time, was raring to turn the master bath into a tranquil spot worthy of a boutique hotel: a sanctuary where Rex, a professional ballet dancer, could relax after a grueling performance, and Bob, a business consultant, could wind down from his own job-related stress. So the dynamic duo called on Home contributing editor Candice Olson, who gutted the entire lavatory, doubling the space to 13½ by 8 feet by bumping into an adjacent unused closet. She equipped the room with dual sinks; a generous air-bath tub; multiple showers (a handheld, wall-mounted jets, and overhead rain fixtures); a steam system; and storage galore. To steam-proof the area, walls, floor, and lighting recesses were totally wrapped in a watertight membrane. After showering, steam is let out via the door's transom and the new frosted-glass privacy window. For variety, Olson mixed slate-, brown-, and sand-colored glass mosaic wall tiles with 12-by-24-inch chocolate-hued porcelain floor tiles. Radiant floor heating keeps toes toasty. Now, the bath is a luxe spa de deux.
